STEAM-SUPERHEAJIER.

Specification of Letters Patent.

Patented Aug. 29, 1916.

Application filed February 27, 1915. Serial No. 11,036.

To nZZ whom it may concern:

Be it known that 'l, Enwua) A. Gmcnn- GAS, a citizen of Great Britain, residing in the borough of Manhattan. city of New York, in the county of New York and State of New York, have invented certain new and useful. Improvements in Steam-Superheaters; and I dodiereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, f0rming part of this specificatiton.

My invention relates to steam superheaters, and consists in the improvements hereinafter pointed out and explained.

The features of my invention are illustrated in the accompanying drawings, in which Figure 1, is a section of a portion of a boiler setting with a. portion of a steam boiler and a super-heater in place therein, according to my invention. Fig. 2, is a transverse section of the same, on the line wm in Fig. 1, looking in the direction of the arrow. Fig. 3, is a view, showing a superheater placed in a boiler setting, according to my invention, in combination with a horizontal tubular boiler. Fig. 4, is a plan view, partially in section of. the tubes and headers shown in Figs. 1, 2 and 3.

In these drawings, A, indicates the tubes of a horizontal water-tube boiler, A, indicates the rear-end header therefor; B indicates the fire wall at the rear end of the furnace grates, (not shown) B, indicates the rear wall of the boiler-setting, B indicates the combustion chamber, and B indicates the side walls thereof.

In the side walls B of the boiler setting, I provide recesses C, which communicate with the combustion chamber B, back of the fire-wall. B, and in these recesses C, I place in an inclined position, super-heater headers, D, each or which is preferably composed of a plurality of independent chambers d, cl and d, and d and (D, said headers being connected by means of: tubes D, extending from one to the other transversely through said combustion chamber, the said headers D, and tubes D, being higher at the rear end of the combustion chamber B, than at the front end thereof. The recesses C, are close hv means of plates or doors C so as to exclude cold air from the combustion chamber B 'Steam 15 introduced into the chamber (1 through the inlet E, and after traveling through the tubes D, enters the chamber d, of the opposite header D, (see F 1g. 4) and thence through the tubes D into the chamber d and thence through the tubes D into the chamber d, and lastly through the tubes D, into the chamber (1, from whence it passes to the outlet E, of the superheater. The heated gases from the furnace travel rearward of the fire-wall B, over the super-heater tubes, and then upward past the rear end of the battle-wall a, and while so traveling, heat the super'heater tubes D, D", D and D.

It will be obvious to those skilled in the art, that by this arrangement I can obtain the benefit of a moderate drying heat for superheating steam within the tubes D, D, D and D, without exposing the tubes to such excessive heatas to injure them, and necessitate a replacing of the same with new tubes.

It will also be obvious that by reason of the intake end of the headers D, being lower than the discharge ends thereof, the superheater tubes D, do not receive the full force of the heat immediately back of the firewall, and that the tubes D, at the rear end of the combustion chambenbcing higher, do receive the full force of the heat, so that as the steam travels back and forth through the tubes D across the combustion chamber, it increases in temperature and is subjected to a gradually increasing temperature from without the tubes D. This arrangement is necessary because as the steam raises in temperature it requires more intense heat to raise its temperature higher.

Having thus shown and described my invention, what I claim as new, and desire to secure by Letters-Patent, is:-

1. In a steam superheating apparatus, a steam boiler, a fire wall, a rear wall, side walls, tube headers located in inclined posi tions in said side walls, with the ends thereof adjacent to said fire-wall being lower than the ends adjacent to said rear wall, and steam conveying tubes parallel with said fire-wall and connected with said inclined headers, substantially as set forth.

2. In a steam superheater, a steam boiler, a fire-wall, a rear wall, side walls, a plurality of tube-header chambers located in each of said side walls between said fire-wall and said rear wall, in parallel inclined positions, superheater tubes parallel with said fire wall connecting the header chambers in one side wall with the header chambers in the opposite side wall, so that steam will be conducted back and forth from the header chambers at one side, to the header chambers at the other side, until it has traversed allot the chambers and tubes behind said firewall, substantially as described.

In testimony whereof I afiix my signature, in presence of two witnesses.
